Page 420 Positioning Data
When the start No. for a current value change (No.9003) is used
In Current value change ([Cd.3] Positioning start No. = 9003), [Md.20] Current feed value is changed to the address set in
[Cd.9] New current value.
■ Operation chart
The current value is changed by turning on Positioning start signal after the new current value is set in [Cd.9] New current
value and 9003 is set in [Cd.3] Positioning start No.
■
Restrictions
• When the unit setting is degree and the specified value is out of the setting range, Outside new current value range (Error
code: 1997H) occurs.
• If the specified value is out of the software stroke limit range, Software stroke limit (+) (Error code: 1994H) or Software
stroke limit (-) (Error code: 1996H) occurs.
• The current value cannot be changed while the stop command and M code ON signal are on.
• The M code output function is invalid.
